POLYTECH develops new smart technology for the extrusion machine with remote control system. We are one of the pioneer who adopt this technology into the extrusion machine. In the past 25 years, POLYTECH never stop doing research and investment for the new technology. Not only some extrusion expert’s filed, also some market new trend knowledge . We cooperate with some big group companies, who have deep understanding and experience for the smart technology. With this new technology, we already improve much on the automatic system. Now the labor cost, management cost. Powder cost, etc, all increase a lot in all of the world. We adopts smart technology into pp hollow sheet machineone year before. It has big welcomed in the market. Most of people face the problems: no experienced technician, high cost of employee, high cost of machine maintenance,etc. POLYTECH give our customer whole solution for this new project. We will also continue to improve it.

PP hollow sheet machine can make PP hollow sheet with diffierent thickness, what’s application it is ?

Product Application

Machine name: PP Hollow Construction Formwork Porduction Line
Finished product : PP Construction Formwork , PP Formwork for Concrete Mould

image007(001)

Product Advantages:

No.1. Smooth and clean.The splicing of the formwork is strict and smooth, and the surface degree and finish of the concrete structure after demolishing exceed the technical requirements of the existing clear water formwork.
No.2. Portable and easy to install.Light weight, strong process adaptability, can saw, planer, drill, nail, can be composed of any geometric shape, to meet the needs of various shapes of building die.
No.3. Simple stripping.Concrete does not stick to the surface, no need of demolishing agent, easy demolishing, easy to remove ash.
No.4. Stable weather resistance.High mechanical strength, in - 20 ℃ to + 60 ℃ temperature conditions,not wet bilge, no crack, deformation, stable size, alkali resistant anticorrosive, waterproof, flame retardant from rat pest control.
No.5. Beneficial to maintenance.Templates do not absorb water, no special maintenance or storage.
No.6. High variability.Types, shapes and specifications can be customized according to the requirements of construction projects.
No.7.Reduce costs.More times of turnover, plane mold turnover more than 50 times, column and beam mold not less than 40 times, low cost.
No.8. Energy saving and environmental protection.Scrap and waste templates can be recycled, zero waste discharge.
